TECHNOLOGICAL FIELD

Example embodiments of the present disclosure relate generally to providing electronic infrastructure on paper documents and, more particularly, to systems and methods for providing electronic authentication of handwriting on paper documents.

BACKGROUND

Modern technology has led to a promulgation of electronic documents. However, certain paper-based documents, such as paper-based financial documents (e.g., loan and mortgage documents, checks, and other financial instruments), remain popular among users of those documents. For example, in the United States and in many parts of the world, people are very comfortable with paper-based financial documents and, in many instances, trust paper-based financial documents with handwritten signatures more than electronic financial documents with digital or electronic signatures. Even if trust in electronic financial documents were to increase, it might take many years before the entire collection of financial documents that have an attached value could become completely digitized.

BRIEF SUMMARY

Systems, apparatuses, methods, and computer program products are disclosed herein for authenticating handwriting (e.g., signatures, writings, stamps, seals) on paper-based documents. The signature authentication system provided herein solves the above problems by providing for a paper-based document that includes an embedded chip for storing document identification information in association with signature authentication metadata generated by a remote authentication server device in response to a handwritten signature on the document.

In one example embodiment, a system is provided for authenticating handwriting on paper-based documents. The system may comprise a paper-based document comprising an embedded chip device configured to be in communication with a signature device. The embedded chip device may comprise electronic memory comprising document identification information indicative of an identity of the paper-based document.

DETAILED DESCRIPTION

Some embodiments of the present disclosure will now be described more fully hereinafter with reference to the accompanying figures, in which some, but not all embodiments of the disclosures are shown. Indeed, these disclosures may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

Overview

As noted above, methods, apparatuses, systems, and computer program products are described herein that provide for authenticating handwriting on paper-based documents. Traditionally, people are very comfortable with paper-based financial documents and trust paper-based financial documents with handwritten signatures more than electronic financial documents with digital or electronic signatures. Further, even if people began to increase their trust in electronic financial documents, it might take many years before the entire collection of financial documents that have an attached value could become completely digitized. Accordingly, the inventors have identified a latent need for a system wherein people may continue to use paper-based financial documents while enjoying the added benefits of electronic infrastructure, such as embedded chip devices, that provide for, among other benefits, increased trust in those documents; increased speed of transactions based on those documents; and more efficient management of identities and values associated with those documents.

In some embodiments, the present disclosure relates to providing electronic infrastructure on paper documents for identity and value management. In general, the present disclosure relates to a signature authentication system for authenticating handwriting, such as signatures and writings, on paper-based documents, such as checks. In some embodiments, the signature authentication system disclosed herein manages electronic infrastructure, such as an embedded chip devices that include radio frequency identification (RFID) and cryptography functionalities, on top of paper-based documents to provide for increased trust in those documents in addition to managing identities and associated values of those documents more efficiently.

In some embodiments, the signature authentication system disclosed herein provides for electronically capturing, in real-time, paper-based handwritten signatures along with other handwritten elements, such as the recipient, date, value (e.g., monetary value), comments, and alterations. In some embodiments, the signature authentication system disclosed herein provides for electronically verifying, in real-time, the captured paper-based handwritten signature for its authenticity. In some embodiments, the signature authentication system disclosed herein provides for electronically associating the signature with the document online along with the other metadata. In some embodiments, the signature authentication system disclosed herein provides for encoding a cryptographic representation of the signature along with other metadata in the paper-based document itself so that the document is verifiable offline. Other metadata may include, for example, timestamps, locations, mash-up locations, biometric information of the people who provided the handwriting (e.g., via signature devices, electronic pen devices, or both), unique device IDs, unique paper IDs, signer names, signer unique IDs, associated current values of the documents, other data or electronic information, and combinations thereof. In some embodiments, the signature authentication system disclosed herein subsequently provides for automatically transferring, in real-time, the value of the document, or the rights associated with the document, to the recipient without additional user input.

In some embodiments, the signature authentication system disclosed herein provides for generating electronic information verifying the authenticity of a signature on a paper document and storing authentication information in a chip embedded in the paper document. In some embodiments, the signature authentication system disclosed herein provides for recording the authentication information while the user signs the document. For example, the signature authentication system may capture a fingerprint via an electronic pen device and a picture or video of the signing of the paper via a separate imaging device. In some embodiments, the signature authentication system disclosed herein provides for transmitting the authentication information to an authentication server device for verification, after which the authentication information is transmitted to and stored in the chip embedded in the signed paper document.

In some embodiments, the signature authentication system disclosed herein provides for gathering electronic information about the signature and the signer, verifying that information at a server, and storing verified information in a chip embedded in the signed document. In some embodiments, the signature authentication system disclosed herein provides for storing information about the signature in the chip embedded in the paper. In some embodiments, the signature authentication system disclosed herein provides for using a separate server that authenticates gathered electronic information about the signature and the signer and then provides corresponding authentication information for storing in the chip embedded within the paper. In some embodiments, the signature authentication system disclosed herein provides for server authentication of recorded data gathered while signing a physical document and the subsequent embedding of authentication information received from the server within a chip in the physical document itself. In some embodiments, the signature authentication system disclosed herein provides that the chip interfaces with a signature device, such as a signing pad or smartphone, for validating user signatures.

There are many advantages of these and other embodiments described herein, such as: avoiding traditional problems surrounding electronic financial documents and paper-based financial documents; increasing trust in paper-based financial documents with electronic infrastructure; providing for continued use of paper-based financial documents while increasing trust in those documents, increasing the speed of transactions based on those documents, and more efficiently managing identities and values associated with those documents; preventing fraud (e.g., ensuring that shareholder dividend checks are accurate and have not been tampered with); and more quickly and easily digitizing paper-based financial documents that have an attached value. Further, because the embodiments disclosed herein process and verify (e.g., authenticate) handwritten signatures and other information on paper-based documents in real-time, or near real-time, those documents carry increased trust and thus, in many instances, can be transacted immediately.

In this regard, FIG. 1 discloses an example environment 100 within which embodiments of the present disclosure may operate to authenticate handwriting provided by one or more users on one or more paper-based documents 110. As illustrated, a signature authentication system 102 may be connected to one or more authentication server devices 104 in communication with one or more databases 106. The signature authentication system 102 may be connected to one or more signature devices 120 through one or more communications networks 108 (e.g., the Internet, a wireless local area network (LAN), a virtual private network (VPN), a cellular network, other types of networks). The one or more signature devices 120 may be connected to one or more embedded chip devices 112 and one or more electronic pen devices 130, and the one or more embedded chip devices 112 may be connected to the one or more electronic pen devices 130, using any of a number of wireless personal area network (PAN) technologies, such as Bluetooth® v1.0 through v5.0, Bluetooth Low Energy (BLE), infrared wireless (e.g., IrDA), ultra-wideband (UWB), induction wireless transmission, Wi-Fi, near field communications (NFC), Worldwide Interoperability for Microwave Access (WiMAX), radio frequency (RF), RFID, or any other suitable technologies or proximity-based communications protocols.

In some embodiments, the signature authentication system 102 may be configured to generate authentication information indicating that handwriting (e.g., a writing, a signature) provided on a paper-based document 110 has been authenticated (e.g., verified as authentic) as described in further detail below. Although referred to herein as a “signature” authentication system, it will be understood that the signature authentication system 102 may be more broadly considered to be a handwriting authentication system.

The signature authentication system 102 may be embodied as one or more computers or computing systems and may comprise one or more authentication server devices 104 and one or more databases 106. The one or more authentication server devices 104 may be embodied as one or more servers, remote servers, cloud-based servers (e.g., cloud utilities), processors, or any other suitable server devices, or any combination thereof. The one or more authentication server devices 104 receive, process, generate, and transmit data, signals, and electronic information to facilitate the operations of the signature authentication system 102. The one or more databases 106 may be embodied as one or more data storage devices, such as Network Attached Storage (NAS) devices or separate databases or servers. The one or more databases 106 include information accessed and stored by the signature authentication system 102 to facilitate the operations of the signature authentication system 102. For example, the one or more databases 106 may store user account credentials and authentic handwriting samples for users of one or more paper-based documents 110, one or more embedded chip devices 112, one or more signature devices 120, one or more electronic pen devices 130, or one or more combinations thereof. In another example, the one or more databases 106 may store data regarding device characteristics of various embedded chip devices 112, signature devices 120, electronic pen devices 130, or combinations thereof. In some embodiments, the user may have captured his or her handwritten signature, signature stamp, signature seal, handwriting samples, and biometric samples ahead of time using a user device. Example embodiments of the user devices include any of a variety of stationary or mobile computing devices, such as a portable digital assistant (PDA), mobile telephone, smartphone, smartwatch, smart speaker, tablet computer, laptop computer, desktop computer, kiosk computer, electronic workstation, any other suitable computing device, or any combination of the aforementioned devices. The user may user the user device to transmit that information to the signature authentication system 102, which may store that information in one or more databases 106 for use in subsequent authentication, by one or more authentication device servers 104, of signature information and writing information for signatures and writings claimed to have been provided by the user on one or more documents 110.

The one or more paper-based documents 110 may be embodied by any suitable paper-based document. For example, the paper-based document 110 may be a negotiable instrument, such as a check. In some embodiments, the paper-based document 110 may comprise one or more embedded chip devices 112. For example, the paper-based document 110 may comprise an embedded chip device 112 configured to be in communication with a signature device 120, an electronic pen device 130, or both.

The one or more one or more embedded chip devices 112 may be embodied by any suitable computing device. In some embodiments, the embedded chip device 112 may comprise an RFID chip with suitable processing power, secure memory, and the ability to connect securely to other devices located nearby (e.g., using wireless PAN technologies). In some embodiments, the embedded chip device 112 may be disposed on (e.g., on an exterior surface of), in (e.g., on an interior surface of, between two surfaces of), or near (e.g., in close physical proximity to) a paper-based document 110. The embedded chip device 112 may be configured to be in near field communication with a signature device 120. In some embodiments, the embedded chip device 112 may be disposed on an exterior surface of the paper-based document 110. In some embodiments, the embedded chip device 112 may comprise embedded chip device may be disposed on an interior surface the paper-based document. In some embodiments, the embedded chip device 112 may be configured to be in near field communication with the signature device 120, and the signature device may be configured to be in network communication with the authentication server device 104.

The one or more embedded chip devices 112 may comprise electronic memory comprising document identification information indicative of an identity of the paper-based document, such as one or more pre-determined elements about the document. The document identification information may comprise one or more document IDs, document numbers, unique identification information, or any other suitable information. In some embodiments, the document identification information may comprise a set of metadata elements that varies for each type of document. For example, the document identification information for a check may comprise a first set of metadata elements, the document identification information for a stock certificate may comprise a second set of metadata elements, and the document identification information for a will may comprise a third set of metadata elements, wherein the first, second, and third sets of metadata elements are different. In some embodiments, the embedded chip device 112 may have different read/write access levels for data stored by the embedded chip device 112. For instance, where the paper-based document 110 is a contract, the embedded chip device 112 may be configured to be read-only on a forward-looking basis. Alternatively, where the paper-based document 110 is a laboratory notebook page, the embedded chip device 112 may be configured for read-write access. In some embodiments, the paper-based document 110 may be a multi-page document wherein each page comprises a separate embedded chip device 112.

The one or more signature devices 120 may be embodied by any suitable computing device. In some embodiments, a signature device 120 may be embodied as an Internet connected device with a touch sensitive pad that can be used to sign the paper-based document 110 using the electronic pen device 130. The signature device 120 many have NFC communications capabilities (e.g., an electronic reader device) to request and receive information from, and transmit information to, the embedded chip device 112, the electronic pen device 130, or both. The signature device 120 many have network communications capabilities to request and receive information from, and transmit information to, the signature authentication system 102 and the authentication server devices 104. In some embodiments, the signature device 120 may be embodied as a user device (e.g., a mobile device such as a smartphone or a smartwatch). In some embodiments, the signature device 120 may have a imaging device (e.g., a camera) that captures the signature information, writing information, and/or biometric information for handwriting provided by the user on the paper-based document 110 using the electronic pen device 130 or any other suitable writing device (e.g., an ink-based pen, a pencil, a stamp, a seal). Although referred to herein as “signature” devices, it will be understood that the one or more signature devices 120 may be more broadly considered to be handwriting processing devices.

Information received by the signature authentication system 102 from the one or more signature devices 120 may be provided in various forms and via various methods. For example, the one or more signature devices 120 may be laptop computers, smartphones, netbooks, tablet computers, wearable devices, desktop computers, electronic workstations, or the like, and the information may be provided through various modes of data transmission provided by these signature devices. In some embodiments, the one or more signature devices 120 may include or store various data and electronic information associated with one or more users. For example, the one or more signature devices 120 may include or store user information, signature information, writing information, biometric information, authentication information, or a combination thereof. In some instances where the paper-based document 110 is a check, the signature information may comprise a signature provided by the payer; a signature provided by the payee; an endorsement provided by the payee that restricts how the check can be used; or a combination thereof. In some instances where the paper-based document 110 is a check, the writing information may comprise a handwritten date of the check; a handwritten name of the payee; a handwritten value of the check in numerical format; a handwritten value of the check in word format; a handwritten memo or note; or a combination thereof.

In embodiments where a signature device 120 is a mobile device, such as a smartphone or tablet, the mobile device may execute an “app” (e.g., a thin-client application) to interact with the signature authentication system 102, one or more authentication server devices 104, one or more embedded chip devices 112, one or more electronic pen devices 130, or a combination thereof. Such apps are typically designed to execute on mobile devices, such as tablets or smartphones. For example, an app may be provided that executes on mobile device operating systems such as Apple Inc.'s iOS, Google LLC's Android®, or Microsoft Corporation's Windows®. These platforms typically provide frameworks that allow apps to communicate with one another and with particular hardware and software components of mobile devices. For example, the mobile operating systems named above each provide frameworks for interacting with location services circuitry, handwriting processing circuitry, biometric processing circuitry, wired and wireless network communications interfaces, user contacts, and other applications in a manner that allows for improved interactions between apps while also preserving the privacy and security of individual users. In some embodiments, a mobile operating system may also provide for improved communications interfaces for interacting with external devices (e.g., embedded chip devices, electronic pen devices, authentication server devices). Communication with hardware and software modules executing outside of the app is typically provided via APIs provided by the mobile device operating system.

The one or more electronic pen devices 130 may be embodied by any suitable electronic handwriting device, such as a biometric smart pen comprising force sensors, pressure sensors, accelerometers, gyroscopes, motion sensors, fingerprint scanners, electrocardiogram devices, iris imaging devices, and other suitable components. In some embodiments, the electronic pen device 130 may be configured to capture biometric information (e.g., speed, acceleration, angle, force, pressure, fingerprint, electrocardiogram, iris information) of a user while the user is using electronic pen device 130 to handwrite on paper-based document 110 and transmit the captured biometric information to the signature device 120.

In an illustrative set of embodiments, a user may place a paper-based document 110 comprising an embedded chip device 112 on the signature device 120. For example, where the signature device comprises a touch-sensitive pad, the user may lay the paper-based document 110 on the signature device 120 in such a way the writable portion will be on the top of the touch-sensitive pad (as shown in FIG. 3). In another example, where the signature device comprises an imaging device, the user may lay the paper-based document 110 on the signature device 120 in such a way the writable portion will be visible to the imaging device (as shown in FIG. 4). As soon as the paper-based document 110 is placed on the signature device 120, the embedded chip device 112 securely connects with the signature device 120 and transmits document identification information to the signature device. The document identification information may be indicative of an identity of the paper-based document.

Next, the user may provide handwriting on a surface of the paper-based document 110. The signature device 120 may generate signature information, writing information, or both and transmit that information to the embedded chip device 112, the authentication server device 104, or both. The signature information may be indicative of a signature provided by a user on a surface of a paper-based document comprising the embedded chip device. The writing information may be indicative of a writing provided by a user on a surface of a paper-based document comprising the embedded chip device. For example, as soon as the user signs or writes on the document, the signature device 120 captures the signature or writing, along with other information from a touch-sensitive area of the signature device 120, an imaging device of signature device 120, the sensors of the electronic pen device 130, or a combination thereof. The electronic pen device 130 may also capture the user's biometric information and transmit the captured biometric information to the signature device 120.

Then, the signature device 120 securely connects with the signature authentication system 102. The signature device 120 encrypts the document identification information, signature information, writing information, biometric information, or a combination thereof and securely transmits the encrypted information to the signature authentication system 102, which receives decrypts that information for analysis by authentication server device 104. The authentication server device 104 determines whether to authenticate (e.g., verify) the signature or writing based on the document identification information, the signature information, the writing information, the biometric information, or a combination thereof.

In some embodiments, the user may have previously provided authentic signature information (e.g., signature samples) to the signature authentication system 102, which may store the user's authentic signature information in database 106. Subsequently, the authentication server device 104 may receive signature information claimed to have been provided by the user on a paper-based document 110, retrieve the authentic signature information from database 106, and determine whether to authenticate the document based on a comparison (e.g., a correlation) of the received signature information and the authentic signature information.

In some embodiments, the issuer of the paper-based document 110 may have previously provided authentic document information (e.g., authentic document identification information, authentic monetary values, authentic terms) to the signature authentication system 102, which may store the authentic document information in database 106. Subsequently, the authentication server device 104 may receive document information claimed to be associated with the paper-based document 110, retrieve the authentic document information from database 106, and determine whether to authenticate the document based on a comparison (e.g., a correlation) of the received document information and the authentic document information. For example, the authentic document information may comprise a monetary value (e.g., $10.00), and the received document information may comprise a different monetary value (e.g., $100.00). In response to determining that the received monetary value does not correspond to the authentic monetary value, the signature authentication system 102 may generate authentication information indicative of the authentic monetary value (e.g., $10.00).

In some embodiments, the user may have previously provided authentic writing information (e.g., handwriting samples) to the signature authentication system 102, which may store the user's authentic writing information in database 106. Subsequently, the authentication server device 104 may receive writing information claimed to have been provided by the user on a paper-based document 110, retrieve the authentic writing information from database 106, and determine whether to authenticate the document based on a comparison (e.g., a correlation) of the received writing information and the authentic writing information.

In some embodiments, the user may have previously provided authentic biometric information (e.g., biometric samples) to the signature authentication system 102, which may store the user's authentic biometric information in database 106. Subsequently, the authentication server device 104 may receive biometric information claimed to have been provided by the user when signing or writing on a paper-based document 110, retrieve the authentic biometric information from database 106, and determine whether to authenticate the document based on a comparison (e.g., a correlation) of the received biometric information and the authentic biometric information.

If the authentication server device 104 determines that the signature or writing is authentic, the authentication server device 104 generates authentication information indicating that the signature or writing has been authenticated. The authentication information may comprise an electronic confirmation or acknowledgement that the signature or writing is valid. Subsequently, the signature authentication system 102 transmits the authentication information to the signature device 120. The signature device 120 then transmits the authentication information to the embedded chip device 112. The embedded chip device 112 receives the authentication information and stores, in the electronic memory: the signature information and the authentication information as signature authentication metadata in association with the document identification information; and the writing information and the authentication information as writing authentication metadata in association with the document identification information. As a result, the embedded chip device 112 contains cryptographically secured proof of the validity and authenticity of signatures and writings on paper-based document 110, as well as other information about the document, such that forgery is nearly impossible. In some embodiments, the signature authentication system 102 may provide for authenticating signatures and writings on multiple types of paper-based documents 110. In some embodiments, the signature authentication system 102 may provide for authenticating multiple signatures and writings by multiple users in the same paper-based document 110.

Having described specific components of example devices involved in the present disclosure, example procedures for authenticating handwriting are described below in connection with FIG. 5.

Example Operations for Authenticating Handwriting

FIG. 5 illustrates an example flowchart 500 that contains example operations for authenticating handwriting on paper-based documents according to an example embodiment. The operations illustrated in FIG. 5 may, for example, be performed by one or more components described with reference to signature authentication system 102 shown in FIG. 1; by an embedded chip device 112, a signature device 120, or an electronic pen device 130 in communication with signature authentication system 102; by apparatus 200 shown in FIG. 2; by an embedded chip device 312, a signature device 320, or an electronic pen device 330 shown in FIG. 3; by an embedded chip device 412, a signature device 420, an imaging device 422, or an electronic pen device 430 shown in FIG. 4; or by any combination thereof. In some embodiments, the various operations described in connection with FIG. 5 may be performed by the apparatus 200 by or through the use of one or more of processing circuitry 202, memory 204, input-output circuitry 206, communications circuitry 208, handwriting processing circuitry 210, biometric processing circuitry 212, authentication circuitry 214, cryptographic circuitry 216, authentication storage circuitry 218, any other suitable circuitry, and any combination thereof.

As shown by operation 502, the embedded chip device (e.g., embedded chip device 112, 312, 412) may be implemented in an apparatus 200 that includes means, such as communications circuitry 208 or the like, for receiving signature information from a signature device (e.g., signature device 120, 320, 420) in communication with the embedded chip device. In some embodiments, the embedded chip device may be in near field communication with the signature device. The signature information may be indicative of a signature (e.g., signature 314) provided by a user on a surface of a paper-based document (e.g., paper-based document 110, 310, 410) comprising the embedded chip device. In some embodiments, the apparatus 200 may provide for receiving the signature information from the signature device in real-time or near real-time. For example, the apparatus 200 may provide for receiving the signature information from the signature device less than about one second after the signature was provided by the user on the surface of the paper-based document.

As shown by operation 504, the embedded chip device may be implemented in an apparatus 200 that includes means, such as communications circuitry 208 or the like, for transmitting document identification information to the signature device. The document identification information may be indicative of an identity of the paper-based document. In some embodiments, the embedded chip device may comprise electronic memory (e.g., memory 204) comprising the document identification information. In some embodiments, the apparatus 200 may transmit the document identification information to the signature device for transmission to an authentication server device (e.g., authentication server device 104). In some embodiments, the apparatus 200 may provide for transmitting the document identification information to the signature device in real-time or near real-time. For example, the apparatus 200 may provide for transmitting the document identification information to the signature device less than about one second after the signature information was received from the signature device. In some embodiments, the signature device may not transmit the signature information to the embedded chip device until after the authentication by the authentication server device. In some embodiments, the signature information is never provided to the embedded chip device, and all that the embedded chip device receives from the signature device is a token (e.g., an electronic token generated by the authentication server device) that can be provided (e.g., through the signature device or a different signature device) back to the authentication server device for verification.

As shown by operation 506, the embedded chip device may be implemented in an apparatus 200 that includes means, such as communications circuitry 208 or the like, for receiving authentication information from the signature device. The authentication information may indicate that the signature has been authenticated by an authentication server device (e.g., authentication server device 104) in communication with the signature device based on the document identification information and the signature information. In some embodiments, the signature device may be in network communication with the authentication server device over a communications network (e.g., communications network 108).

As shown by operation 508, the embedded chip device may be implemented in an apparatus 200 that includes means, such as authentication storage circuitry 218 or the like, for storing the signature information and the authentication information as signature authentication metadata in association with the document identification information.

In some embodiments, operations 502, 504, 506, and 508 may not necessarily occur in the order depicted in FIG. 5, and in some cases one or more of the operations depicted in FIG. 5 may occur substantially simultaneously, or additional steps may be involved before, after, or between any of the operations shown in FIG. 5.

In one optional operation, the embedded chip device may be implemented in an apparatus 200 that includes means, such as cryptographic circuitry 216 or the like, for encrypting the document identification information, the signature information, and the authentication information. The apparatus 200 may further include means, such as authentication storage circuitry 218, for storing encrypted signature information and encrypted authentication information as encrypted signature authentication metadata in association with encrypted document identification information.

In another optional operation, the signature may be provided by the user on the surface of the paper-based document using an electronic pen device (e.g., electronic pen device 130, 330, 430) configured to obtain biometric information indicative of an identity of the user. In some embodiments, the electronic pen device may be in communication with the signature device and configured to transmit the biometric information to the signature device for transmission to an authentication server device, an embedded chip device, or both. In some embodiments, the electronic pen device may be in communication with the embedded chip device and configured to transmit the biometric information to the embedded chip device. In some embodiments, the embedded chip device may be implemented in an apparatus 200 that includes means, such as communications circuitry 208 or the like, for receiving the biometric information from the signature device or the electronic pen device. In some embodiments, the apparatus 200 includes means, such as communications circuitry 208 or the like, for receiving the authentication information from the signature device, wherein the authentication information indicates that the signature has been authenticated by the authentication server device based on the document identification information, the signature information, and the biometric information. In some embodiments, the apparatus 200 includes means, such as authentication storage circuitry 218 or the like, for storing the biometric information, the signature information, and the authentication information as the signature authentication metadata in association with the document identification information.

In yet another optional operation, multiple users may provide multiple signatures on the paper-based document. For instance, in operations 502-508 described above, the user is a first user, the signature is a first signature, the signature information is first signature information, the authentication information is first authentication information, and the signature authentication metadata is first signature authentication metadata. In some embodiments, the embedded chip device may be implemented in an apparatus 200 that includes means, such as communications circuitry 208 or the like, for receiving second signature information from the signature device. The second signature information may be indicative of a second signature provided by a second user on the surface of the paper-based document. In some embodiments, the apparatus 200 includes means, such as communications circuitry 208 or the like, for receiving second authentication information from the signature device, wherein the second authentication information indicates that the second signature has been authenticated by the authentication server device based on the document identification information and the second signature information. In some embodiments, the apparatus 200 includes means, such as authentication storage circuitry 218 or the like, for storing the second signature information and the second authentication information as second signature authentication metadata in association with the document identification information.

As noted above, methods, apparatuses, systems, and computer program products are described herein that provide for authenticating handwriting on paper-based documents. By doing so, people are able to avoid the traditional problems surrounding signature authentication in paper-based financial documents (e.g., loan and mortgage documents, checks, and other financial instruments). For instance, through performance of the above operations, people can gain increased trust in paper-based financial documents with electronic infrastructure, such as an embedded chip device. Further, through performance of the above operations, people can continue to use paper-based financial documents while enjoying the added benefits of increased trust and more efficient management of identities and associated values of paper-based financial documents provided by the electronic infrastructure disclosed herein. Further still, through performance of the above operations, paper-based financial documents that have an attached value may become digitized more quickly and easily. For example, because the embodiments disclosed herein process and verify (e.g., authenticate) handwritten signatures and other information on paper-based documents in real-time, or near real-time, those documents carry increased trust and thus, in many instances, can be transacted immediately.

FIG. 5 thus illustrates a flowchart describing the operation of various environments (e.g., environment 100 described with reference to FIG. 1), systems (e.g., signature authentication system 102 described with reference to FIG. 1, system 300 described with reference to FIG. 3, system 400 described with reference to FIG. 4), apparatuses (e.g., apparatus 200 described with reference to FIG. 2), methods, and computer program products according to example embodiments contemplated herein. It will be understood that each operation of the flowchart, and combinations of operations in the flowchart, may be implemented by various means, such as hardware, firmware, processor, circuitry, and/or other devices associated with execution of software including one or more computer program instructions. For example, one or more of the procedures described above may be performed by execution of computer program instructions. In this regard, the computer program instructions that, when executed, cause performance of the procedures described above may be stored by a memory (e.g., memory 204) of an apparatus (e.g., apparatus 200) and executed by a processor (e.g., processing circuitry 202) of the apparatus. As will be appreciated, any such computer program instructions may be loaded onto a computer or other programmable apparatus (e.g., hardware) to produce a machine, such that the resulting computer or other programmable apparatus implements the functions specified in the flowchart operations. These computer program instructions may also be stored in a computer-readable memory that may direct a computer or other programmable apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture, the execution of which implements the functions specified in the flowchart operations.

Use Cases

Having described example embodiments in general terms, the following example embodiments are provided to further illustrate a use case of some example embodiments. In some instances, the following example embodiments provide examples of how the signature authentication system disclosed herein may authenticate handwriting on a paper-based document. Further, the embodiments disclosed herein may be extended to multiple use cases, such as mortgage documents, loan documents, power of attorney documents, and other documents.

“Check” Use Case

“Check” is an illustrative example use case wherein the signature authentication system disclosed herein may authenticate writings and signatures on a check that includes an embedded chip device and automatically transfer, in real-time, the check value to the payee without additional user input. First, a payer may write a payee name, date, amount, and comments (e.g., notes, memos) on the surface of a check and sign the check. The signature device may generate writing information indicative of the writings provided by the payer on the check. The signature device may further generate signature information indicative of the signature provided by the payer on the check.

The signature device may also receive document identification information for the check from the check's embedded chip device. For example, the check's embedded chip device may store document identification information comprising a check number; an account number (e.g., a checking account number, a savings account number); a routing number; financial institution information (e.g., name, address, phone number, website); logos or icons; a date of the check; a value (e.g., currency amount) of the check in numerical format; a value of the check in word format; a memo or note; personal information (e.g., name, address, phone number, email address, unique IDs (e.g., social security number (SSN), taxpayer identification number (TIN), employer identification number (EIN), financial institution member number)) and other information about the payer (i.e., the account owner, the person writing the check) and the payee (i.e., the person or entity to whom the check is payable); or any combination thereof.

The signature device may encrypt the document identification information, the signature information, and the writing information and transmit the encrypted information to an authentication server device associated with the payer's financial institution. The authentication server may decrypt and analyze the document identification information, the signature information, and the writing information and generate authentication information based on the document identification information, the signature information, and the writing information. The authentication information may indicate that the check has been validated by the payee's financial institution. In some instances, the authentication information may be an electronic token.

The authentication server device may transmit the authentication information back to the signature device, which may in turn transfer the authentication information to the check's embedded chip device. As a result, the check will include the traditional writings and signature of the payer as well as an electronic confirmation of the check's authenticity in the form of a confirmation from the payee's financial institution stored in the check's embedded chip device. The recipient of the check (i.e., the payee) can then simply use their financial institution's mobile wallet (e.g., a mobile wallet app executing on the recipient's smartphone) and deposit the check in their bank account. The check value will be transferred instantly because the signature is already verified and validated. Accordingly, there is no need for the payee to take pictures of the front and back of the check in order to deposit the check in the payee's account. Rather, as the check comes in close proximity to the payee's mobile wallet, the mobile wallet picks up the check and prompts the user whether or not to deposit the check.

In some embodiments, the signature device may transfer the signature information and the writing information to the embedded chip device, which may add that information to the document identification information. For example, in addition to the authentication information, the signature device may transmit the signature information (e.g., the signature handwritten by the user on the check) and the writing information (e.g., the date, payee name, check amount in numerical format, check amount in word format, and memo or note handwritten by the user on the check) to the embedded chip device, which may add that information to the document identification information or otherwise store that information in association with the document identification information.
